JAMES H. THOMPSON, OF TRENTON, NEW JERSEY, ASSIGNOR TO HUSSONG DYEING MACHINE COMPANY, OF GROVEVILLE, NEW JERSEY, A CORPORATION OF NEW JERSEY.

DYEING MACHINE.

To (/ZZ whom it may concern.

Be it known that I, JAMES H. TrroMrsoN,

a citizen of the United States, residing in Trenton. Mercer County, New Jersey, have invented certain Improvements in Dyeing Machines, of which the following is a specification.

One object of my invention is to design a vat of a dyeing machine, in which liquor is circulated first in one direction and then in the opposite direction, so that there will be an even flow of the liquor throughout the stock under treatment.

A further object of the invention is to design the cage, in which loose stock is being treated, so that the stock will be tumbled and rearranged during the dyeing operation, assuring a more accurate coloring, or treat- 9 ment of the stock.

- In the accompanying drawings:

Fig. 1 is a longitudinal sectional view of a dyeing vat, showing a cage in position therein;

Fig. 2 is a side view of the cage, showing the bottom doors in the open position;

F Fig. 3 is a sectional view on the line 33,

Fig. 4 is a longitudinal sectional view illustrating a modification of the construction of the vat;

Fig. 5 is a transverse sectional view on the line 5--5, Fig. 4;

Fig. 6 is a longitudinal sectional view of a yarn rack, which can be used in connection with the vat shown in Figs. 1 and 4:; and

Fig. 7 is a sectional View on the line 7-7, Fig. 6.

Referring to the drawings, 1 is a dye vat made in the usual manner and having at one end a circulating compartment 2, which is separated from the dyeing compartment 3 by a partition 4-. This partition stops short of the top and bottom of the vat and forms upper and lower circulating passages. ,5 is a propeller, which is mounted on a shaft 6 that is driven in any suitable manner.

The driving mechanism in this type of dyeing machine is so designed that it can be reversed so that the direction of the flow of liquor in the vat can be reversed.

In the bottom of the vat is a series of transverse deflectors 7. These deflectors ex- Application filed April 3, 1924. Serial No. 703,939.

tend from one side ot the vat to the other and are preferably of difi'erent heights. The deflector farthest from the circulating compartment 2 is greater in height than the deflector nearest the circulaing compartment so that the liquor, when flowing in the direction of the arrow, is directed by the deflectors up through the stock. The angle of each deflector is more acute on the side facing the circulating compartment than on the opposite side so as no to interfere with the free flow of liquor towards the circulating compartment when the direction of movement of liquor is the reverse of that indicated in Fig. 1.

The cage 8 is of the ordinary construction and is of such a size as to fit in the dyeing compartment 3 and has solid sides 9 and ends 10. The bottom consists of a series of doors 11. which are hinged to the body and can be held in a closed position by any suitable device. The cage is suspended from beams 12, which rest upon the edges of the vat.

On the inner side of the cage are longi' tudinal deflectors 13, which are V-shaped in cross section, as shown in Fig. 3. These deflectors are for the purpose of tumbling, or rearranging, the stock under treatment when the stock is forced from the bottom of the cage to the top thereof, or vice versa, insuring a more thorough treatment of the stock than in a cage in which the deflectors are omitted. Instead of the deflectors 7 in the bottom of the vat shown in Fig. 1, rotating members 7 may be used, having blades as shown in Fig. 4-. In front of the rotating members are baflies 7 which direct the course of the liquor as it flows from the propeller and under the stock so that it will strike the bottom paddles of the rotating members, causing the rotating members to throw a certain portion of liquor up through the stock under treatment.

lVhile a vat used in connection with a cage is illustrated in 1. in some instances, the cage may be omitted and a rackmay be substituted therefor, as shown in Figs. 6 and 7 The rack has side members 14, which are attached to cross beams 15. In each of the side members are slots 16 for the sticks 17, on which the hanks of yarn are suspend ed. Above the yarn sticks is a series of spaced bars 19, which tend to distribute the liquor in circulation. The rack is provided with a cover 20, which is secured thereto in any suitable manner. Directly below the sticks 17, on which the hanks of yarn are mounted, are longitudinal ribs 21 that project inwardly from each side member 14. These ribs tend to prevent the yarn from being carried into the slots by the sticks and pinched between the yarn sticks and the side walls of the slots. \Vhcnever this pinching occurs, that part ot the hank that is pinched is not thoroughly impregnated with the dye, or bleaching, liquor. The strips keep the yarn from coming in contact with the side members and prevent the yarn being carried into the slots. The upper surface of each longitudinal rib is beveled and is on a line with the bottom of the slots so that the yarn sticks can be readily inserted in position.

I claim: I

1. The combination of a dye at; means for circulating liquor in the vat: and a series of transverse deflectors in the bottom of the vat below the material being dyed,v said deflectors being arranged to direct the liquor through the material located in the vat.

2. The combination of a dye vat; means for circulating liquor in the vat; transverse deflectors at the bottom of the vat; and a cage located in the vat above the deflectors, said cage having longitudinal deflectors on each side wall.

The combination ot a dye vat having a dyeing conq'iartment and a circulating compartment; means for circulating liquor in the vat: and a series of deflectors in the bottom of the vat, said deflectors increasing in height from the circulating compartment to the opposite end of the vat.

it. The combination of a dye vat having a dyeing compartment and a circulating compartment; means for circulating liquor in the vat: and a series of transverse deflectors at the bottom of the circulating compartment of the vat, each deflector having an abrupt bevel on one side and a long bevel on the opposite side. the abrupt bevel portion ot the deflectors facing the circulating compartment.
